A team of geologists at the University of Houston College of Natural Sciences and Mathematics believes they have found the lost plate in northern Canada by using existing mantle tomography images—similar to a CT scan of the earth's interior. The findings, published in Geological Society of America Bulletin, could help geologists better predict volcanic hazards as well as mineral and hydrocarbon deposits.
"Volcanoes form at plate boundaries, and the more plates you have, the more volcanoes you have," said Jonny Wu, assistant professor of geology in the Department of Earth and Atmospheric Sciences. "Volcanoes also affect climate change. So, when you are trying to model the earth and understand how climate has changed since time, you really want to know how many volcanoes there have been on earth."
Wu and Spencer Fuston, a third-year geology doctoral student, applied a technique developed by the UH Center for Tectonics and Tomography called slab unfolding to reconstruct what tectonic plates in the Pacific Ocean looked like during the early Cenozoic Era. The rigid outermost shell of Earth, or lithosphere, is broken into tectonic plates and geologists have always known there were two plates in the Pacific Ocean at that time called Kula and Farallon. But there has been discussion about a potential third plate, Resurrection, having formed a special type of volcanic belt along Alaska and Washington State.
Using 3-D mapping technology, Fuston applied the slab unfolding technique to the mantle tomography images to pull out the subducted plates before unfolding and stretching them to their original shapes.

Yes, well, he has a sense of humor but she only shines with reflected light. Still, she’s creative, and the idea was a good one.
You’re right: “_ _ _ to the World” does seem a little pushy. I’ll bring it to their attention in my next letter. ;o]
Your Tall Son and my Tall Son are very much alike in their senses of humor and but for the age difference they could be great friends. Or maybe the age difference wouldn’t matter. Fun to contemplate, at any rate.
I defeated the Son (and DP and Vlad) at Scrabble. Second time in a row!
Marmalade squee!
Good morning.
The shower has been had and the tea is ready, and then, after I’ve checked a few things, I’ll write to Charlie. I also have to write a letter to the Short Child, as there are things I need to tell her that don’t do well as text messages.
It rained last night, but I don’t know how much. There may or may not be snow on Pine Mountain. I’ll find out when I go to do my errands.
Hooray for you!!! I can’t recall the last time I played Scrabble. L-o-n-g time ago!
Good morning. It was a busy night with cats in and out. Pat is off work today; maybe I can get the other parent to take him on a Driving Adventure.
I slept hard. I believe the actual count was six hours without interruption. A record, I believe.
When the alarm rang, I was dreaming of looking at a starry sky with a strange male-type person. A good omen.
The letter to Charlie is done so I’ll take it over to the mailbox and take the trash out on my way.
There are some calls I need to make this morning before I head for my errands, and I’m getting tired of calling AR. But I’ll keep calling until the end of the month and then another letter will go out. I suspect there will be a flurry of activity shortly thereafter, in that small town...;o]
Best wishes on the day!
We have friends of Kathleen’s coming over to make (more) cookies today, so I need to clean up the kitchen.
Mmmm...Cookies!!
I’m going to try and get the cheese ball made today. Maybe I’ll make two! I have enough stuff.
It just depends on how I feel between now and when I have to leave. I’m hoping I’m only gone about 30-45 minutes because I’m very tired. *whine*
My daughter and her friend once made a line of greeting cards based on woes and lamentations from the Bible during a bored weekend.
They didn’t sell.
It is Friday. Happy Friday.
We got rid of 2 feet of snow on and around our cars yesterday afternoon so we can move them at appropriate times when our parking lot needs to be cleared. We have 3 zones and they clear zone 1, then zone 2, then zone 3. Cars are supposed to move to the not active zones but I’m not sure there are enough spaces because COVID. The plan is designed for many cars being off in a commute.
Our cars are in zone 3 right now.
Maybe they just didn’t have the timing right.
My mother sent snaps, taken by his wife, of my brother shoveling snow yesterday.
How funny!
I could never think of anything good enough to be inside of a card, except for my signature. ;o]
Happy Friday!
No snow here (maybe on the mountain, but I can’t see it from here) but it rained last night. When I went out to mail the letter to Charlie, the air was so clean and fresh it almost took my breath away.
Now, though, the wind is up so it will be a lot colder than it was 90 minutes ago. And it looks like a sunny day ahead, though the forecast is for gloomy skies later on.
OK, I’ll bite: How do you move your cars for the snow to be cleared, if there is enough snow to keep you from moving your cars?
Followup question: If there isn’t enough snow to keep you from moving your cars, does it really need to be removed?
There’s a full color glossy with circles and arrows and a paragraph on the back ... wait, wrong story.
See, when they start, they will start with Lot 1. So before 8am you should get your car out of Lot 1 into Lot 2 or Lot 3 (which are not clear). Or you can come down at 8 and move your car out into the driving lanes and wait until your space is done, then move it back.
Once Lot 1 is done, people in Lot 2 move to either Lot 1 or Lot 3 so Lot 2 can be cleared.
Then it’s Lot 3’s turn.
Oh, where did the driving lane snow get pushed? Over to the east side. You aren’t supposed to park there. If you did ... boy are YOU gonna have an un-merry Christmas. That pile’s at least 20 feet high.
So, you can move your cars.
If there isn’t so much snow that you can’t move your cars, does it really need to be removed?
My brother (MD) and sister (MI) both sent photo’s of snow-covered back porches.
But GA had snow before either of them!
Then again, it wasn’t much snow and didn’t stay for long ....
Yeah. “Installer” for the storm doors and the rest of the house stuff = me, in this abode.
